ENGINE-TIMER.

Application filed July 8, 1919,Ser1al 1T0. 309,413.

To all whom. it may concern:

Be it known that I, PHILLIP J. DELL, J r., a citizen of the United States, residin at Va cross, in the county of Ware and S nate of "eorgia, have invented certain new and useful Improvements in Engine-Timers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to new and useful improvements in attachments for internal combustion engines and has for one of its objects the provision of means whereby the timer or commutator can be mounted for operation at a distant point from the end of the cam shaft and still be driven thereby instead of being located in close proximity to the end of the cam shaft as at present thus obviating the inconveniences of manually lubricating the commutator or timer owing to its inaccessible location at present and its liability of interfering with the fan and fan belt.

Another object of this invention is the provision of an attachment for internal combustion engines of the above stated character, which shall be simple, durable and efficient, and which may be manufactured and sold at a. comparatively low cost.

With these and other objects in view as will become more apparent as the description proceeds, the invention consists in certain novel features of construction, combination, and arrangement of parts as will be hereinafter more fully described and claimed.

For a complete understanding of my invention, reference is to be had to the following description and accompanying drawing, in which Figure 1 is a front elevation of an attachment for internal combustion engines constructed in accordance with my invention and illustrating the same applied to an en me g 2 is a vertical sectional view of the attachment,

Fig. 3 is a detail view of the means for securlng the commutator or timer cap in lace p Fig.4 is a transverse sectional view taken through the timer cap or shell'illustrating the contact roller and the manner of mounting the same.

Specification of Letters Patent. Patented J l 26 1921 Renewed December 27, 1920. Serial No. 433,521.

Referring in detail, the numeral 1 indicates a cover plate for the timing gears of the engine 2 and is of the usual construction having an opening 3 to receive the end of the cam shaft 4 on which is mounted a bevel gear 5. ormed upon the cover 1 and about the openlng 3 is a housing 6 provided with a removable cover7. The housing 6 has an upwardly and outwardly extending tubular member 8 formed thereon having located 111 each end bearings 9 that rotatably support a shaft 10. The shaft 10 has a bevel gear 11 secured to one end and located within the housing 6 and in mesh with the gear 5. The tubular member 8 is supported in an upwardly inclined position by means of brackets 12 which is secured to the cover plate 1. An annular member 13 is formed on the upper end of the tubular member 8 and is adapted to form a seat for a commutator shell 14. of an ordinary construction provided with the usual contact 14.. The upper end of the shaft projects beyond the annular member 13 within the shell and has mounted or secured thereto a contact roller 15. The contact roller 15 is mounted or journaled to one end of an arm 16 that is pivoted between a pair of arms 17 formed on the collar splined or otherwise secured to the upper end of the shaft. The arm 16 has a spring 19 secured to its other end which spring is in turn connected to a lug formed upon the collar. The apex of the shell is provided with the usual recess 20 to receive one end of a locking rod 21. The locking rod 21 is slidably mounted within apertured lugs 22 formed upon the tubular member 8 and is offset as clearly shown in the drawing so that said rod can extend about the annular portion 13 and the shell to engage in the recess 20. A coil spring 23 is mounted upon the rod 21 between the lugs 22 and has one end secured to the rod while its other end bears against one of the lugs so that said rod is placed under tension for securely holding the shell against the annular portion.

From the foregoing description taken in connection with the accompanying drawing, it will be noted that the timer or distributer is mounted at a convenient point whereby necessary repairs can be conveniently made to the same and also can be easily lubricated when desired. It is also to be noted that the device can be readily applied to an internal combustion engine of a certain type without altering the construction and ope 'ation of the engine.

lVhile I have shown and described the preferred embodiment of my invention, it will be understood that minor changes in construction, combination, and arral'igement of parts may e made Without departing from the spirit and scope of the invention as claimed.

Having thus described my invention, What I claim is z- An attachment for engines including a timing gear cover and a cam shaft a housing formed on the cover, a tubular member formed on said housing a timing shaft journaled in said tubular member and housing and connected to the cam shaft, an annular portion formed on the upper end of the tubular member, a timer shell mounted on said annular portion, a contact roller carried by the timing shaft and operating Within the shell, spaced apertured lugs formed on the tubular member a spring actuated locking rod mounted in said lugs and having its free end curved to engage the shell.

In testimony whereof I atfix my signature in presence of two witnesses.
